New pending patent applications are published on Thursdays by the PTO. Both of this week's Spotlight Applications concern aspects of digital fingerprinting. Assigned to Georgia Tech, the first application discloses techniques for detecting call provenance from call audio. Assigned to Samsung (KR), the second application discloses a server apparatus and method of transmitting finger print thereof, and broadcast receiving apparatus.
20150257001, "Systems and methods for detecting call provenance from call audio," assigned to Georgia Tech Research Corporation.
Abstract
Various embodiments of the invention are detection systems and methods for detecting call provenance based on call audio. An exemplary embodiment of the detection system can comprise a characterization unit, a labeling unit, and an identification unit. The characterization unit can extract various characteristics of networks through which a call traversed, based on call audio. The labeling unit can be trained on prior call data and can identify one or more codecs used to encode the call, based on the call audio. The identification unit can utilize the characteristics of traversed networks and the identified codecs, and based on this information, the identification unit can provide a provenance fingerprint for the call. Based on the call provenance fingerprint, the detection system can identify, verify, or provide forensic information about a call audio source.20150256905, "Server apparatus and method of transmitting finger print thereof, and broadcast receiving apparatus," assigned to Samsung (KR).
Abstract
A server apparatus includes a receiver configured to receive content, a data detector configured to detect a plurality of fingerprints from at least one of image data and voice data of the content, a controller configured to generate a fingerprint set selected as different fingerprints in consideration of similarity between the plural fingerprints, and a communicator configured to transmit the generated fingerprint set to a broadcast receiving apparatus.
